Forgot to snap a pic, but my hot idle (Around 550) was at 41 PSI after about an hour on the road yesterday. That's with the current "leftovers" fill which is PUP 0W40, RL 0W40, and like half a quart of I forget which 5W30. I knew it would be a short OCI (Still wrapping up my move/house selling adventure) since I've been making a lot of 150+ mi round trips in the last two months and I needed to use up all those leftover spare quarts/partials. Since the 5.7's been running so well on the 0W40 amalgamation I'm tempted to just go with straight RL 0W40 next change or try the 6.4 on RL 5W40 and spread the rest of my RL 0W40 out mixed with RL 5W30 over the next few 5.7 changes.
